DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a recording / reproducing apparatus.

[0002]

2. Description of the Related Art There is a hard disk as a large-capacity storage device, and a hard disk used in a personal computer has been reduced in cost and capacity. So, C
Digital audio data such as music recorded in D is transferred to a hard disk for recording.

[0003] By doing so, for example, only a desired song can be selected from a large number of songs provided by a CD and left on the hard disk. You can copy it to an MD and listen to it.

[0004]

However, when digital audio data of a song is transferred from a CD to a hard disk and recorded, data recording of the song such as the title of the song becomes a problem. That is, in an audio CD, the P channel of the subcode is used for cueing, and the Q channel is used for information relating to absolute time and the like.

Further, in a standard called "CD text", additional character information of the CD is recorded in the R to W channels included in the track in the lead-in area of the CD. The record of this character information is 65
Although about 00 bytes are possible, it is assumed that the character information per CD is 800 bytes or less, so that it can correspond to languages of eight countries.

The character information is the album name (C
D name), performer name (conductor name, orchestra name, etc.),
The names are lyricist name, composer name, song name (track name), message, search keyword, and the like. These pieces of information are recorded using character codes such as so-called shift JIS.

Therefore, when music is transferred from a CD to a hard disk and recorded, if the CD text is also recorded on the CD, data relating to the music such as the music title can be easily recorded on the hard disk.

[0008] However, there are CDs on which no CD text is recorded, and in the case of such a CD, it is necessary to input data relating to music from a keyboard, which is troublesome.

When data is transferred from a CD to a hard disk and recorded, a CD player (CD-ROM drive) whose read speed is twice or four times the standard read speed is often used. . For this reason, songs can be transferred and recorded from the CD to the hard disk in a short time. However, while data about the song is being input from the keyboard, the transfer / recording of the song ends, and editing is performed later. There must be.

[0010] The present invention is to solve the above problems.

[0011]

According to the present invention, there is provided a disk reproducing apparatus for reproducing digital audio data from a disk, a large-capacity storage device, and an operation unit, wherein the disk reproducing apparatus reproduces digital audio data from the disk. When the digital audio data is transferred to the mass storage device for recording, or when the digital audio data is recorded, it is determined whether or not data relating to a song to be reproduced by the digital audio data is written to the disc. When data relating to a song reproduced by digital audio data is written, data relating to the song is recorded in the mass storage device, and when data relating to a song reproduced by the digital audio data is not written, The above data input through the operation unit In accordance with the information to identify the disk,
This is a recording / reproducing apparatus in which data relating to the music is obtained from the outside and recorded in the mass storage device. Therefore, data relating to the music recorded in the mass storage device is also recorded.
